Stochastic optimization in AIMMS
Kůdela, Jakub ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
Tato diplomová práce uvádí základní poznatky matematického a především stochastického programování. Navíc se zabývá použitím softwaru AIMMS při vytváření a řešení optimalizačních problémů. Naším hlavním cílem je naprogramovat v softwaru AIMMS několik metod řešení problémů stochastického programování a ukázat jejich použití a užitečnost na vybraných problémech. Jedním z problémů, který jsme si zvolili, je model spalovny. Všechny AIMMS programy, které v našem textu použijeme a popíšeme, a jejich zdrojové kódy budou přiloženy v dodatcích.

Waste management system sustainability
Bravený, Adam ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
The thesis proposes a new approach to assess sustainability of waste management systems. In the first part current mixed municipal waste (MSW) management system of the Czech republic is reviewed and promising MSW treatment techniques are introduced. In the second part a summary of literature on Life Cycle Assessment (LCA) approach to assess sustainability of MSW systems is provided. A new sustainability assessment model is proposed by implementing LCA to a current tool called NERUDA used to optimize waste management costing. It is demonstrated how to connect these two concepts in order to aquire a powerful tool for sustainability assessment.

Incineration of Sludge Mixed with Alkali
Urban, Václav ; Jecha, David (referee) ; Houdková, Lucie (advisor)
Subject of the present Ing. thesis is problem of incineration of sewage sludge and influence of lime on production of editions. In work are described kinds of sewage sludge combustion and possibilities of edition cleaning. Work includes design and description of experimental combustion of sewage sludge mixtured with kalcite in fluidized bed reactor. The end of work delal with, evaluation of editions from combustion experiment. Evaluated components of bunt gases are: heavy metals, TZL, SO2, CO, CO2, HCl, HF, O2, NO, PAH, PCB, PCDD/F.

Life cycle assessment of municipal waste
Vlach, Josef ; Slavík, Jan (referee) ; Jícha, Jaroslav (advisor)
The aim of this study is to present methodology life cycle (LCA) and Life Cycle Assessment of disposal the municipal solid waste chain. There is described the procedure of generation of the LCA studies according to the standards ČSN EN ISO 14 040 and ČSN EN ISO 14 044 in the first and second part. In the third part of this diploma there are described LCA analyses that have already been created. The software GEMIS (Global Emission Model for Integrated System) is described in the fourth part. The computer model GEMIS has been used as a calculation tool in this study. The fifth part of this study includes waste management and different kinds of disposal municipal solid waste. In this part is describe basic data about landfilling and incieration. There is shown LCA analysis of disposal municipial solid waste in the sixth part. Data processing was carried out by means of the software GEMIS 4.3. The results were interpreted for incineration and landfilling. Finally there is mentioned results for 1 TJ different elektrical energize to.

Energy recovery of waste
Vala, Michal ; Baláš, Marek (referee) ; Moskalík, Jiří (advisor)
The first part of this thesis sums up problems arising from waste production and compares different ways and technologies of waste treatment. Second part of this thesis focuses on one of these ways, on the incineration of waste with energy recovery. It discusses specifics and possibilities of this technology and describe current situation in the Czech Republic.

Energetical utilization of waste, especially sewage sludge
Havlásek, Martin ; Kuba, Pavel (referee) ; Frýba, Lukáš (advisor)
This bachelor´s work discusses about energetical utilization of sewage sludge. The process is described from sludge treatment to flue gas cleaning. The main emphasis is on incineration, which are governed by legislation. First are listed sludge treatment and utilization technology which included thermal processing in which is thoroughly described the process of incineration. The following are methods for co-incineration of sludge and devices for direct incineration. Work is finished by chapter about flue gas cleaning.

Biodegradable waste
Dřímal, Jiří ; Niesner, Jakub (referee) ; Beňo, Zdeněk (advisor)
The goal of this bachelor is introduction with the issue of using biodegradable waste (BDW) in the EU. The introductory chapters are focused on the description of the different types of BDW. There are described ways of processing of this waste and their use. The emphasis is on mapping the current condition of treatment of biodegradable waste with it in the EU and the CR.

Thermal treatment of waste with heat recovery
Strapko, Tibor ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Following bachelor‘s thesis deals with one of the possible way of waste treatment nowadays, thermal treatment, focusing on the facilities using this secondary raw materials as a renewable source of energy, WTE plants (incinerations plants in history). At the beginning this work focuses on waste and its history, diversification, characteristics, origin and reasons of their continual grow in production. For complexity and possibility of comparison this work slightly deals with 2 other most popular ways of waste treatment, as well: recycling and waste disposal. Next part concers with thermal treatment of waste, specializing on WTE plants and its processes. These can be devided into 3 different parts: incineration part, energy utilization part and flue gas cleaning part. Big attention is concentrating on energy utilization system, which inconsiderable affects general effectivity of this facilities. Finnaly, there‘s a numerical evaluation of energy flows in process of waste incineration and its processing into simple block and computational model.

Potential of energy production from waste
Putna, Ondřej ; Ferdan, Tomáš (referee) ; Touš, Michal (advisor)
The main topic of the bachelor thesis is creating energy from the incineration of waste. In the first part, the current situation of waste management of the Czech Republic and other states of the Europian Union is outlined. Then the thesis is focused on waste incineration in waste-to-energy plants and various approaches of energy efficiency evaluation are described. In the second part, energy efficiency with various modes of thermal and electrical energy production is analyzed, using the model of WtE plant. In conclusion, obtained data of energy efficiencies are compared with conventional energy sources.

Legislature of the waste disposal and utilization of biodegradable materials
Pešl, Milan ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
The aim of this work is to give information about the issue of legislation of disposal and reuse of biodegradable waste. Legislation in the field of bio-waste in the Czech Republic and the EU is grouped into various laws and guidelines which describe particular conditions of the dumping of wastes, their subsequent processing and reuse. In this work, the definition of BDW, its composition and the current state of dealing with this type of waste in the EU and the Czech Republic is mentioned. Different methods of processing biodegradable waste, which include incineration, composting and anaerobic digestion, their advantages and disadvantages are described in this work. There are also introduced examples of BDW in the EU and the Czech Republic there.
